This document describes the features and characteristics of the VIPER16 fixed frequency VIPerTM plus family, including 800 V avalanche rugged power section, PWM operation with frequency jittering for low EMI, no need of auxiliary winding for low power application, standby power < 50 mW at 265 VAC, etc.
The VIPER16 is a fixed-frequency power controller from the VIPER plus family designed for off-line converters. It features an 800 V avalanche rugged power section and operates with frequency jittering to reduce EMI. The device eliminates the need for an auxiliary bias winding by powering itself directly from the rectified mains, supporting applications such as power meters, LED drivers, and auxiliary power supplies.
